"When ModernAnalyst asked me to propose an article for their issue on Enterprise Architecture, I thought about the question framework developed by John Zachman, that provides the basic building blocks of that practice. The primary function of a Business Analyst is to ask questions that uncover requirements then to document those requirements so they may be developed into a useful, useable system. It seemed to me that questions are a common thread for the Enterprise Architect, Data Architect, and Business Analyst alike. As the conversation progressed, I realized that I could reach out to John Zachman and pose a few questions to him about Enterprise Architecture. This article will be split between a brief interview, Q&A with John Zachman, and a more detailed overview, Data Architecture..."

"LORETTA: Which Framework classifications (aka Cells) would be most relevant for the Business analysts and why?
JOHN: Someone has to transcribe what the Executive Leaders of the Enterprise have in mind as to the boundaries of the Enterprise relative to the Inventories they control, the Processes they perform..."
"LORETTA: How can the Business Analysts use the primitive interrogatives (what, how, where, who, when and why) when performing enterprise analysis?
